Detection and counting of individual free-swimming krill using a 2MHz scanning sonar

The euphausiid crustacean Meganyctiphanes norvegica (M. Sars) have been detected and counted in the scanning section of a 2 MHz scanning sonar beam up to 3 meters from the sonar head. The tests completes a pilot investigation on equipment needed to study krill behaviour in relation to sampling gears...
